\qmltype QtObject \instantiates QObject \inqmlmodule QtQml

A basic QML type.

The QtObject type is a non-visual element which contains only the objectName property.

It can be useful to create a QtObject if you need an extremely lightweight type to enclose a set of custom properties:

import QtQuick
Item {
QtObject {
id: attributes
property string name
property int size
property variant attributes
}
Text { text: attributes.name }
}

It can also be useful for C++ integration, as it is just a plain QObject. See the QObject documentation for further details.

\qmlproperty string QtObject::objectName This property holds the QObject::objectName for this specific object instance.

This allows a C++ application to locate an item within a QML component using the QObject::findChild() method. For example, the following C++ application locates the child \l Rectangle item and dynamically changes its color value:

\qml MyRect.qml 

import QtQuick 2.0

Item {
    width: 200; height: 200

    Rectangle {
        anchors.fill: parent
        color: "red"
        objectName: "myRect"
    }
}
\endqml

\code
// main.cpp

QQuickView view;
view.setSource(QUrl::fromLocalFile("MyRect.qml"));
view.show();

QQuickItem *item = view.rootObject()->findChild<QQuickItem*>("myRect");
if (item)
    item->setProperty("color", QColor(Qt::yellow));
\endcode
